The Case for Mass Slaughter of Predators Just Got Weaker

Wildlife officials in Washington State recently green-lit a controversial plan to kill a pack of wolves fingered as the culprits behind a spate of attacks on cows there. The way the state sees it, taking out the carnivores could help prevent more livestock losses.
The United States used this justification to kill thousands of coyotes, wolves, bears, and other predators last year. Other nations, including Canada and Finland, have also authorized predator hunts for this reason.
But these killings might not solve any problems after all. A new study published Thursday in the journal Frontiers in Ecology and the Environment found that there's little scientific evidence that killing predators actually accomplishes the goal of protecting livestock.
"We know anecdotes and perceptions don’t get us very far when we’re dealing with a problem like livestock predation," says Adrian Treves, a conservation biologist from the University of Wisconsin who co-authored the paper. "The science of predator control has been slow and not very advanced."
Treves and his colleagues reviewed previous research attempting to measure the effectiveness of various predator-control methods in North America and Europe. Some studies looked at whether killing predators meant fewer livestock deaths, while others examined the success of nonlethal deterrents, such as the use of guard dogs and flag-lined ropes or wires.
The scientists found that most of the research doesn’t hold up scientifically. Only two of the studies were deemed top notch because they took into consideration the possible effects of things like disease, weather and other elements that could influence livestock deaths. But neither study focused on the effectiveness of killing predators...more

That the National Geographic would p!mp this garbage from a sworn carnivore fetishist without providing a copy of the actual paper simply shows why National Geographic is no longer worth the subscription. What a shame.
